4 Claims.

My invention relates to the handling of film such as is employed formotion picture purposes,

' 4and has among its objects and advantages the provision of an improvednlm magazine for use in connection with either cameras or projectors.

An object of my invention is to provide a lm magazine which is loadedwith film at the place of manufacture or finishing, in which themagazine is designed to provide a light-proof and protective housing forthe lm and in which the lin may be effectively unwound from the magazineand simultaneously Wound thereon during exposure or projection of thefilm. The exposed or projected lm Will be completely wound inside themagazine after which the unit may be transported to the developingfacilities or the film exchange.

A further object is to provide a film magazine in which the lm isconvoluted inside the magazine and in which novel means are incorporatedto facilitatev withdrawal of the convoluted film in an easy andeffective manner and at the same time permitting return of the lm to themagazine for convoluted storage therein and without the necessity forreversal by rewinding.

Figure 11 is a sectional view along the line II-II of Figure 1; and

Figure 12 is a fragmentary sectional view of one of the magazine rollersillustrating the manner in which the film is convoluted between aplurality of such radial rollers, and the manner 5 Figure 9, at whichtime the projection' 60 snaps in which the film edges are separated andsupported by thebulging of the rubber surfaces of said rollers.

In the embodiment selected to illustrate my invention, I make use of amagazine IIJ which comprises side walls I2 and i4 and a central hub I6.Side walls I2 and I4 are arranged in spaced and parallel relation andeach wall includes an inwardly. extending peripheral flange I8. SideWalls I2 and I4 are also provided with radially aligned semi-circulargrooves 20 for substantially housing radial rollers 22. Shortersemi-circular grooves 24 are also provided in the inner faces oi' theWalls I2 and I4 to substantially house radial rollers 26 somewhatshorter than the rollers 22. According to Figure 2, the rollers 22 and26 project slightly beyond the inner faces of the walls I2 and I4 andare so spaced as to provide accommodation for the convoluted film 28.

Each of the long rollers 22 and the short rollers 26 has its outer endrotatably journaled at 30 in one of the peripheral flanges I8, while theshort rollers 26 are rotatably journaled at 32 in one end wall of theirrespective grooves 24. The inner ends of the long rollers 22 arerotatably journaled at 34 in the hub structure I6. Figure'12 illustratesthe specific construction of the rollers 22 and 26. The roller of Figurel2 includes an aluminum tube 36 provided with end plugs 38, only one ofwhich is illustrated, each provided with a shaft 40 for rotatablymounting the roller.

` Tube 36 is venclosed in a rubber tube 42 relatively xed thereto so asto afford a irictional and cushioning surface against which the edges ofthe lm convolutions 44 bear, making spaced indentations therein.

Referring to Figures 8 and 9, the peripheral flanges I8 have offsetfaces 46 and 48, while the walls I2 and I4 have flanges 50 extendingbeyond the faces 48. A cover 52 lies on the faces 46 and is providedwith offset' flanges 54 which lie on the faces 48. The y'cover is in thenature of a split band with its ends overlapping, as at 56. Figure 9illustrates the overlapping ends, the lower of which is provided with anupstanding projection 68 receivable within the recess 58 in the outeroverlapping end. The outer overlapping end conforms in general contourto the end therebeneath and is bent to provide laterally extendingflanges 62 which fit in the groove formation 64 in the lower end. Theanges 62 fit snugly in the grooves 64 and are slidable therein so thatthe overlapping ends of the cover may be effectively latched whenbrought together in the manner of into the rcccss 56 for effectivelyconnecting the cover ends. The cover has close fitting relation with thefaces 46 and 40 so as to have light tight relation with the flanges I8.The cover may be provided with a knob 66 to facilitate connection anddisconnection of the cover from the fianges.

In Figure 1, I illustrate the hub structure I6 as being provided withgrooves 6B. which extend longitudinally of the hub structure and atright angles to the grooves 20 and 24. Rollers 10 are disposed withinthe grooves 66 and have their peripheral surfaces projecting slightlybeyond the general hub structure. The rollers 10 are identical inconstruction with the roller illustrated in Figure l2 with respect torubber covering. Figure 2 illustrates the rollers 10 as being rotatablyjournaled at 12 in the hub structure I6. Rollers 10 are arranged incircular formation, as illustrated in Figure 1, to provide a core uponwhich the film 23 is convoluted. Cover 52 is provided with a well 14provided with light sealing material 16 constituting an entrance for thefilm 23, see Figure 10. Well 14 is substantially tangentially arrangedwith respect to the outer circumference of the film convolutions.

Hub structure I6 includes a central bore 18 within which I press abushing 30 having a flange 62 lying ina recess 84 in the outer face ofthe wall |2. Bushing 80 is provided with a socket 86 for the receptionof an axle or support (not shown). The socket is provided with a setscrew 88 for flxedly relating. the hub to the axle so that the magazinemay be revolved in the same manner as existing spool reels for loadingand unloading purposes. Under such conditions, the cover 52 is removed.Bushing 8|) is provided with a pair of spaced rollers 90 between whichthe exit end 92 of Vthe film is threaded. The exit end constitutes theinside convolution of the film wound on the rollers 10 between the twosets of rollers 22 and 26. Bushing 80 also carries two rollers 94 and 96between which the film end 92 is threaded. Under some conditions thefilm end 92 is withdrawn horizontally, as at 98, in which event the filmis moved over the roller 96. In other cases the film might be withdrawnvertically, as at |00, in which event the film end 92 is pulled over theroller 94 and over a roller |02 located so as to hold the vertical runof the film in slightly spaced relation with the wall I4. It will benoted that the film end 92 is twisted ninety degrees about itslongitudinal axis between the rollers 9|] and the rollers 94 and 96.

Above the rollers 90 I provide an exit opening |04 which includesflanges |06 between which I position cushioning material such as blackdyed cotton |08 to provide a light and dust trap for the film. Flanges|06 are slotted at I|0 for the 4reception of a plate II2 slotted at II4for accommodating the film end 92. Plate I|2 constitutes a floor for thematerial |08 and the flanges |06 are arranged in converging relation torelation so as to facilitate insertion of the material |06 which may beformed in the manner of the plug IIB of Figure 4, which plug is slottedat |I8 for accommodating the film end. Material 16 of Figure l mayconstitute a plug which is pressed into the well 14 and provided with aslot |20 for accommodating the film run |22. Complete closure for theplug II6 may be attained through the medium of a door |24 arranged to bepressed into the recesses |26 in the flanges |06 locking the film end 92between the plates |I2 and |24.

Figure illustrates the cover 52 as being provided with lips |28 to whichtwo walls of the well Figure 12.

14 may be welded. The cover is provided with a corrugated run |30against which the end run |22 of the film may be pressed for securingpurposes through the medium of a label strip |32 which is shaped to haveits margins anchored inside the grooves 64 of the cover. It will thus beseen that the label strip |32 constitutes a securing means for the endrun |22 in addition to providing an effective closure for the cover overthe film inlet.

In operation, the magazine constitutes a merchandising package withstoring facilities for the film at the place of manufacture or atfinished film libraries. 'I'he film is convoluted upon the rollers 10,and the diameter of the magazine is such as to provide accommodation forthe necessary length of film. The edges of the film lie in snug relationwith the radial rollers 22 and 26. These rollers are rubber covered soas to provide cushioning and spacing means for the film. While the spacebetween the two banks of rollers is such as to permit rather snugwinding of the lm, the relation is such as to cause the roller surfacesto bulge at frequent intervals, which provides spacing at regularintervals between the convolutions, as indicated generally in However,the rollers rotate freely which is also true of the rollers 10. The filmremains in the magazine through the exposure stage and up to the stageof processing. The magazine is light and dust proof so as to affordprotection for the film.

For projection purposes, the film end 92 is spliced to the end run I 22to provide an endless film. Previous to'splicing, the end 92 is threadedthrough the projection gate of the projector in the usual manner. Duringprojection, the film is pulled from the magazine and projected film isreturned to the magazine to be wound therein. Rollers 10 provide ananti-friction core upon which the inner convolution of the film moveseasily while the spaced nature of the lm is such as to provide freerelative movement between the convolutions in the magazine. Thus thefilm will be spirally wound in the magazine as it is withdrawn therefromfor projection purposes. The cushioned rollers afford protection andspacing for the iilm. After threading of either or both end runs of thefilm through the camera or projector mechanism, the ends are preferablyprovided with beveled ends for splicing purposes.

I provide the magazine with humidifying facilities. Wall I4 is providedwith a V-shaped undercut slot |34 within which I position a spongeelement |36 which may be saturated with suitable organic liqu'ids formaintaining the interior of the magazine under the proper humidifledconditions. Wall I4 is provided with a removable screw plug |36 tofacilitate saturation of the sponge |35. The sponge is spaced slightlyfrom the edges of the convoluted lm so as not to be in direct Contacttherewith. The magazine may be loaded with lm with the cover 52 removedand the hub connected with a suitable mechanism for revolving themagazine in the same manner that existing spool reels are wound. Afterloading, the film ends are made secure in their respective gates and themagazine may then be used as a lm shipping case provided withhumidifying facilities. The magazine may be mounted above, below,horizontally or vertically on projectors, editors, cleaners, processors,printers, sound dubbers, sound cameras, cameras, and camera magazinesprovided with enclosed sprockets and exposure gates.

I claim:

1. In a lm magazine having a lm inlet and a film outletand a core forsupporting convoluted lm, rollers radiating from the core upon bothsides of the magazine and spaced to rec eive the convoluted filmtherebetween, short rollers arranged between the outer ends of the firstmentioned rollers, and yielding faces on said first mentioned rollersengageable with the edges of the convoluted film with sufficientpressure to cause 111m indentation of the facesand bulgly spacedrelation.
